>Description:
Using aio_write with the rt signal notification crashes the system.  3 
different machines have been crashed using this technique.  Note that no
signal number is specified for this test.
>How-To-Repeat:
#include <aio.h>
#include <fcntl.h>

#include <signal.h>
#include <string.h>

int main ( void )
{
	int f;
	struct aiocb io;
	char data [ ] = "Donnees a ecrire\n";
	
	f = open ( "allo", O_CREAT | O_TRUNC | O_WRONLY, 00600 );
	memset ( &io, 0, sizeof ( struct aiocb ) );

	io.aio_nbytes = sizeof ( data );
	io.aio_fildes = f;
	io.aio_buf = data;
	io.aio_sigevent.sigev_notify = SIGEV_SIGNAL;

	aio_write ( &io );

	sleep ( 1 );
	return 0;
